Acronis adding to AMS “The machine has been already registered”

While adding a machine to AMS after restoring a sysprepped image, the adding of the machine to Acronis’ Management Console fails with the error:

The machine has been already registered

This is a quick fix:

1 – Remove the \HKLM\Software\Wow6432Node(on a 64 bit machine)\Acronis\BackupAndRecovery\Settings\MachineManager\MMSCurrentMachineID key

2 – Restart the AcronisScheduler service.

All set.
